Devil Survivor 2 stopped working on Acekard 2i

I've had Devil Survivor 2 working on my acekard 2i for a while now, but suddenly today whenever I try to start that specific ROM, it loads up onto a white screen and stays there.I've formatted my SD card with the Panasonic SD formatter, downloaded a new ROM from here, and even updated my acekard 2i to 1.9.0. However none of it helped and Devil Survivor 2 is so far the only one that's having issues. I do play on a 3ds that's version 4.2, could that possibly be the problem? I think I've played it on there since I updated the Acekard to the 4.2 version though, but I'm not entirely sure.Thank you all for any help.PS. Just tried it in my old DS, and the same problem happens, white screen after trying to load it, so it's not due to the 3DS

Just in case anyone else was having this problem, I got mine fixed. Seems somehow the data for that game's system save or something in AIO got corrupted. By doing another format and getting the latest AIO folder and stuff I got it to work fine again.
